摘要

The bayonet attachment means (16) on the cartridge (12) for the attachment of a mixer or accessory to a multiple component cartridge is formed as a ring-shaped bayonet socket (17) with two internal recesses (18) and two diametrically opposed cut outs (19, 20) forming bayonet retaining means (21), whereas the bayonet attachment means of the mixer (1) or accessory comprises two bayonet lugs (10, 11) corresponding to the cut outs. In a preferred embodiment the lugs and cut outs are of different widths for the coded alignment of the mixer or accessory to the cartridge in one predetermined position only. <IMAGE> <IMAGE> <IMAGE>
